I'm using ffmpeg for transcoding of my videos on a HP Blade dedicated server with these details:
OS: Windows Server 2012 R2 64Bit
CPU: Intel XEON X5650
Hard disk: A sas normal disk
This command is a sample for creating qualities which has 4K as top level and I use this command for creating lower qualities from that as parallel at the same time.
ffmpeg -i input.mp4 -filter_complex [0:v]split=4[s0][s1][s2][s3]; [s0]scale=uhd2160[v0]; [s1]scale=hd1080[v1]; [s2]scale=hd720[v2]; [s3]scale=hd480[v3]; [s4]scale=nhd[v4]; [s5]scale=cga[v5] -map [v0] -map [v1] -map [v2] -map [v3] -map [v4] -map [v5] -map 0:a -c:v libx264 -c:a aac -f tee -g 48 -threads 0 "[select='v\:0,a':f=hls:hls_list_size=0:hls_time=6]../video/2160p/out.m3u8| [select='v\:1,a':f=hls:hls_list_size=0:hls_time=6]../video/1080p/out.m3u8| [select='v\:2,a':f=hls:hls_list_size=0:hls_time=6]../video/720p/out.m3u8| [select='v\:3,a':f=hls:hls_list_size=0]../video/480p/out.m3u8| [select='v\:3,a':f=hls:hls_list_size=0:hls_time=6]video/360p/out.m3u8| [select='v\:3,a':f=hls:hls_list_size=0:hls_time=6]video/200p/out.m3u8"
Some times in transcoding time windows goes to reconnecting and count up to 20 and then goes to black screen. I cannot find anythings in windows logs. And finally I restart server from button of that server. What's hapenning? How can I find a clue, about this issue? Any one know anything about this issue?
